The AmpRx Brownie can tweak your amp’s voltage for maximum tone – and it could be your key to finally unlocking Eddie Van Halen’s coveted ‘Brown Sound’
NAMM 2025: AmpRx has sought to shake things up for tube amp users by releasing the Brownie – a nifty voltage controller tool ...
A recent report from Navigant Research analyzes the global market for dynamic volt/volt-ampere reactive (VAR) solutions and components, including global market forecasts for revenue, segmented by ...
One of the most common requests I get from engineers is for a comparison of voltage-feedback op amps and current-feedback op amps. It is impossible to determine which one better suits a given ...
You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...
The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 Volt car batteries could be used. The input voltage to the regulator must be at ...
Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...
As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...
